But the Kings of Leon star quickly cleared up the gossip, explaining his pal had 'hacked' his Twitter.com account, writing, "Looks like @dougc2001 got me again. Have to start locking my phone. Still on the market."

In a new tweet, Followill writes, "Just to clear something up @dougc2001 is not a hacker. He's a very close friend with whom I am in a prank war with. 1-0 Dougie. I got next.

"I think he has a grandparent's bday party coming up. I'm going to spike his drink with Viagra. 'Come give Gam Gam a hug, little Dougie'."
